Cr-LiF as a high energy density conversion-type cathode for Li-ion solid-state batteries

HR-TEM and respective FFT of the as-deposited Cr-LiF cathode. Green circles highlight nanocrystal domains ~ 1.5 nm in size.

Transition-metal fluorides (TMFs) are attracting attention as alternative lithium-ion battery cathodes, primarily focusing on Fe-based systems.

A fruitful collaborative study between Empa (Swiss Federal Laboratories for Materials Science and Technology) Dubendorf, Switzerland, and Professor Saiful Islam's group, introduces chromium fluorides as a new high-energy conversion cathode, expanding the options of viable materials for next-generation batteries.
